Image 如何使用Gd库在codeigniter中显示动态按钮?
我用动态颜色、字体、按钮大小创建表单。 当我提交表单时,按钮图像以整页显示,我需要显示在第一页本身 我的控制器代码:Image 如何使用Gd库在codeigniter中显示动态按钮?,image,codeigniter,gdlib,Image,Codeigniter,Gdlib,我用动态颜色、字体、按钮大小创建表单。 当我提交表单时,按钮图像以整页显示,我需要显示在第一页本身 我的控制器代码: public function creatorbuton(){ $button_size = $this->input->POST('button_size'); $font_style = $this->input->POST('font_style'); $color_schme = $this->input->PO
public function creatorbuton(){
$button_size = $this->input->POST('button_size');
$font_style = $this->input->POST('font_style');
$color_schme = $this->input->POST('color_schme');
$textdisplay = $this->input->POST('textdisplay');
header('content-type: image/png');
//Create our basic image stream
//125px width, 125px height
$image = imagecreate(120, 60);
//Set the background color
$blue = imagecolorallocate($image, 150, 50, 105);
//Set up another color just to show how the first color declared is used as the background color when we use imagecreate()
//Notice how blue is applied to the background, *not* red.
$red = imagecolorallocate($image, 150, 200, 10);
//$font = myurl.'fonts/arial.ttf';
//$text="Hello";
//imagettftext($image, 20, 0, 11, 21, $red, $font, $text);
//save the image as a png and output
$result_array['final_image'] = imagepng($image);
//Clear up memory used
imagedestroy($image);
$this->load->view('buttonconfig/buttoncreator',$result_array);
如何在buttoncreator视图页面中显示按钮。当我使用取消注释这行时
imagettftext($image, 20, 0, 11, 21, $red, $font, $text);
我得到了这一行“图像我的URL无法显示,因为它包含错误”。我得到了输出:我的代码是
public function creatorparam(){
$bg_color="FF8640";
$text_color="C7FFE3";
$button_width =120;
$button_height =90;
$r_bg = hexdec("0x".substr($bg_color,0,2));
$g_bg = hexdec("0x".substr($bg_color,2,2));
$b_bg = hexdec("0x".substr($bg_color,4,2));
$r_bgt = hexdec("0x".substr($text_color,0,2));
$g_bgt = hexdec("0x".substr($text_color,2,2));
$b_bgt = hexdec("0x".substr($text_color,4,2));
header('content-type: image/png');
$image = imagecreate($button_width, $button_height);
$blue = imagecolorallocate($image, $r_bg, $g_bg, $b_bg);
$red = imagecolorallocate($image, $r_bgt, $g_bgt, $b_bgt);
imagestring($image,18,0,0,$textdisplay,$red);
imagepng($image);
imagedestroy($image);
}
请在以后对代码的格式设置更加小心。如果您的代码易于阅读和理解,您就更有可能得到积极的响应
